Anyone Using an Asus DSL-AC68U

been testing and tweaking :D to make connection super duper stabler :D even though i get no drop outs on default, adding tweaks brings out the fun :D

As you can see i have reduced max rate speed a little, and added more db to the upstream and gained quite a bit in upload max rate sync speed. from 32 to 41 ;)
i have also noticed my ping is more stable and slight reduction and also 0 judder on pingtest compaired to old settings of 1-2 judder.

Just wait until DLM will bite u soon! :D
 
I just tried putting my connection back to Annex B and my attenuation went from 5 to 10!...

Leaving it on A... does anyone know what it should be on because I think I have been synced good and proper on A now and its working well but I have no idea if its A OR B... :confused:

My dsl modem is freaky or it could just be my dslm or exchange equipment cause i cant change from annex b to a no matter what i try lol

i can hard select A but under sync info still shows me as connected to annex b :/
also my line has much less errors now that i have disabled so :UPBO upstream power back off.

that setting disabling it gave me higher upload stability. :D then i used the TX RGC gain at high performance and finally i changed the TX power -2

give it a try, gave me more stability and less cr erroring...

and btw 5-10 is ok before it gives you more play, then you can use the other settings to reduce it and gain even more stability....
i to am not sure what annex to use but at this point i cant select A anyway well i can but it does nothing still connects to B lol

Well I have only 128D/20U crc errors over 13hours. So not bad... I think upbo is a requirement by BT. Note your dbm readings are quite high with it off. I think it controls the power on line to stop crosstalk. It will effect other lines which in turn might trigger lower overall speeds to all if cabinnet disagrees in the future. My annex does the same.. still says A if I select B now. Not sure:confused:
 
Just snagged ones of these for £190 including next day delivery. From what I have been reading a successful connection is a bit hit and miss with some having issues and some not. I can always go back to using the OR modem if need be I guess...
 
Seeing as I'm at home at the moment, I decided to give the DSL-AC68U another go, this time taking the settings that I found over on another forum as ASUS had advised someone. This included the Rx AGC GAIN Adjustment (VDSL) setting being set to Stable, and setting Bitswap to Disabled.

So far, 3 hours with 37 CRC errors downstream / 0 upstream. This is better than the modem has managed in the past so maybe these settings will work for me.
 
I had it on balanced, changing it to stable upped my attenuation downstream from 5dB to 6dB lower the better. I have not tried bitswap yet but I would asume that allowing it to utilise freespace and ease congestion on other channels would be a good thing...

I have however disabled seamless rate adaption. It specifies that if you have a stable connection then you can turn it off for a better data rate.

CRC Error rate is now 20 down / 4 up in a little over 2 hours. SNR has changed to 9.7 down and 23.7 up. I am not sure what the SNR is though. It must be the margin as the graph is showing my SNR in realtime as 50 with dips as low as 30.


*Edit. TX Power is what is changing my Downstream Attenuation... Setting it on +3 = 7dB, +2 = 6dB and +1 is giving me a 5dB down ATT. Whilst anything above +1 = 0dB for my upstream.

Do you have the full list of settings that asus recommended? Or was it only these two changes from default? Now I've been back on the HH5 modem for 3 weeks the DLM has dragged my sync rate back up to normal. I might give it another go with the ASUS modem and the modified settings to see if its any better.
 
well i have just found out that i have a problem with my fibre :(
when ever i receive a call or make a call my DSL light goes out. WTF...

i look at the router when this is happening and under crc download errors i get a rush of errors before i loose dsl sync.... only happens when making or receiving calls...

wonder what that could be caused by seriously....
 
Yeah agree - sounds like a dsl filter issue. Try disconneting all extensions and trying the supplied Asus DSL filter straight in to the master test socket (if you have a bt openreach socket unscrew the faceplate, fit the dsl filter in to the test socket (which you will now see) and connect the router and phone to the filter.

Got mine connected and setup ok, so far, after an hour, no errors and connected at the same speed as the Sky setup...

Hope it goes ok but mine was like yours at the start but I soon had to revert to the Openreach Modem as well. no problems now, I will wait for a stable firmware before I revert back to router only.
 
Thanks, after just over two hours I've 203 crc down and 1 up....

Edit: shot up to over 19k down over three hours and had a disconnect :-( How do I set it up to use the OR modem?

Connect one of the LAN ports to the openreach modem with an RJ45 cable. In the WAN settings, under "Dual WAN" set the "Primary WAN" to ethernet - no other changes needed. In this config you lose a LAN port, and of course are abandoning the VDSL modem that you paid a lot for. I did exactly this and it worked perfectly.

With the lack of a fix appearing anytime soon I returned it and exchanged for an AC87U. There are people who seem to be having success with the DSL-AC68U and I would definitely consider it again if there looks like a reliable across-the-board fix - until then it is a very expensive router - the AC68U does the same (and gives an extra LAN port), the AC78U does more. I stuck with the DSL-AC68U for a few weeks, but if the only way of getting stable performance is to use a spearate modem, you may as well get oa router that is designed for that.
 
Out of interest, how are you finding the 87U? Are you using stock firmware or Merlin firmware?

My last attempt with the DSL-AC68U lasted 6 hours before a re-sync, and then CRC errors racking up at double the previous rate. Thankfully looks like I caught it and DLM did not intervene this time round.

Back in its box and staying there. This time permanently.

RT-AC68U and OR modem works great, the AC87U is tempting but I'm not sure I would gain anything extra over the 68U in terms of wireless speed and options.
 
The AC87U is great but you are right - if I already had the RT-AC68U I'd stick with it. I was "starting from scratch" I thought I may as well try the 87, and it was almost the same money as I got back for the DSL-AC68U. I've noticed that the wifi transfer from my (ac) laptop to my wired server is faster with the AC87U than the DSL-AC68U, but both are so fast it is not really an issue. I prefer the design of the RT-AC68U, but as I say thought I may as well go bells and whistles as hopefully this will serve me for a good while.

Oh and using stock firmware for now, everything is stable and working, speeds back to normal, so haven't felt the need to tinker (probably will at some point). Not really looked in to Merlin for it yet, but looks like its still very early beta, probably will hold of till its more mature.

Thanks for the information, I appreciate your time. Only 23 crc's down in the last seven and a half hours so I will see how it goes. However as I paid only £180 for the dsl-ac68u I will be keeping it as there are some who have had some success with it on other forums.
 
No problem, if I'd have no problem buying it again (DSL-AC68U) if everything gets straightened out. I use mine for work though and just can't afford the risk and disruption while all this gets worked out.

BTW Mine often went 12 hours with zero crc and then would suddenly get a burst and bounce. That was the frustrating thing, it takes so long to test a particular setup, and all the while speeds are creeping down. As you have an OR modem in reserve you have a "get out of jail card" if you need it!
